Hydrogen water dispenser for refrigerator appliances

A refrigerator appliance, comprising:

• an insulated cabinet defining a chilled chamber;
• a door mounted on the cabinet;
• a dispenser mounted on the door;
• a user input positioned at the dispenser;
• and
• a system for infusing hydrogen into water dispensing from the refrigerator appliance, the system comprising:
• a tank defining an interior volume divided into a liquid water portion and a hydrogen gas portion, the liquid water portion being no greater than one liter, the tank comprising a hydrogen outlet and a hydrogen line extending from the hydrogen outlet to the liquid water portion, the hydrogen line being disposed at least in part outside of the interior volume of the tank,
• an electrolysis system comprising an anode and a cathode being disposed entirely within the interior volume of the tank, the anode and cathode configured to decompose water within the interior volume of the tank when a voltage differential is applied across the anode and cathode during a hydrogen infusion cycle of the electrolysis system, the electrolysis system further comprising a polymer electrolyte membrane between the anode and the cathode, the polymer electrolyte dividing the interior volume into the liquid water portion and the hydrogen gas portion, and
• an audio emitter configured to emit an audio alert in response to completion of the hydrogen infusion cycle,
• wherein the tank, the electrolysis system, and the audio emitter are installable within the refrigerator appliance, and
• wherein the tank is disposed within the door.
